AC6A1BA Fireye Actuator

Overview

The Fireye AC6A1BA is a keypad-programmable, direct-coupled modulating rotary actuator motor designed for use in burner and valve control systems. It is typically employed alongside electronic controls to regulate process temperatures by connecting its drive shaft to a butterfly valve stem. This model features an upright keypad orientation, meaning it is intended for vertical mounting with wire connections located at the bottom.

Features

• Solid-state electronics for reliable, precise control.
• Integrated LED display with membrane keys for local manual positioning and parameter setting.
• Direct-coupled design eliminates the need for complex linkages.
• Support for multiple positioning inputs, including 4-20mA, 0-10Vdc, and switch inputs.
• Two auxiliary contacts provided for position feedback.
• Selectable clockwise or counterclockwise rotation.
• NEMA 4 rated construction for protection against environmental elements.

Applications

The Fireye AC6A1BA is used in industrial and commercial combustion systems to regulate the flow of fuel or air. It is specifically designed for burner management systems and valve control, often integrated with butterfly valves in petrochemical, power generation, and oil and gas industries. It serves as a modern replacement for older units like the Eclipse PRA series actuators.
